WAVE-MOTOR.

SPECIFICATION forming part of Letters Patent No. 578,612, dated March 9,1897. Application filed May 19, 1896. Serial No. 592,16 '7. (No model.)

To all whom it may concern:

Be it known that 1, DAVID F. SPANGLER, of Santa Ana, in the county ofOrange and State of California, have invented an Improved Wave-Motor, ofwhich the followingisa specification.

My invention relates to wave-motors, and has for its object theprovision of a motor which will utilize the buoyancy of the waves foroperating the said device.

With this object in view the invention consists of the details ofconstruction and arrangement which will more fully appear hereinafter.

' In the accompanying drawings, which form a part of this application,Figure 1 is a side elevation of my invention in position. Fig. 2 is atop plan view thereof. Fig. 3 is a detail view of the two alternatinglevers and friction-clamps. Fig. 4 is a View of the pier with thecylinder and other mechanism removed.

Fig. 5 is a vertical sectional view showing the pile A encircled by thecylinder B, also showing the flange b and the platform 0, which issecured to the said cylinder and rotates therewith, also showing thecylinder 0, attached to the pile. Fig. 6 is a detail of thefriction-clamp-operating mechanism. Fig. 7 is a side elevation of thesame when the operating-lever F is horizontal. Fig. 8 is a sideelevation of the same when the said lever F is raised upward by thewaves.

Like numerals or letters of reference indicate corresponding parts inthe several views.

Referring to the said drawings, A designates a pier projecting out ofthe water and having a hollow compressed-air cylinder at projecting fromthe top thereof. An annular flange b is suitably placed on the pier, asshown; A cylinder B, having the platform 0 with hole 0, is placed overthe pier A, the lower end thereof working over the annular flangeb.Thehollowcompressed-aircylinder a projects up through the hole 0 andallows the plunger d to work therein.

At one end of the platform 0 is placed an upright standard D, havingbifurcated ends 6, between which is pivoted the end of the lever E. Theupper end of the plunger .61 is pivoted at f to the said lever E.

A lever F is pivoted to the bracket G, said bracket being situated onthe side of the cylinder B, the said lever projecting out into the seaand having attached to the free end of the said lever a buoyant float S.A gear-sup porting frame 11 is secured to the platform 0 and hasjournaled therein the shaft I, said shaft projecting beyond the frameand having keyed to the outer end of said shaft a crank g, the lower endof which is pivoted to the lower end of the pitman J, the upper end ofthe pitman J being pivoted to the bifurcated end h of the lever E. Alarge toothed wheel K is keyed to the shaft 70, said shaft beingjournaled in bearings t', suitably situated in the gear-supportin gframe H, the

said large toothed wheel K meshing with the gear-wheel m, said gearbeing keyed to the shaft I. A flange or rim n is situated on the side ofthe toothed wheel K. At a suitable intermediate point of the lever F ispivoted two rods 0, the upper ends of which being pivoted at p to twofriction-clamps working upon the rim n, so as to produce a continuousrotary motion in one direction of the toothed wheel K, the lever Fbeing. operated by the rise and fall of the buoyant float S.

In the present invention I use a compressedair cylinder for transmittingthe power generated by my invention, but I do not confine myself tosuch, and any other method can be used which will answer the purpose.

In case onefloat does not give speed enough, I will lengthen the mainshaft and put on another friction-wheel and set of levers, and soarranged that when one float is on top of a wave the other will be inthe trough, thus increasing the speed twofold.

The annular flange b, which surrounds the pile A, is made of leather orsuitable material and serves to keep the revolving cylinder B fromcoming in contact with the said pile A except on the said flange, theobject being to lessen the friction between the outer cylinder and thepile A.

The platform 0 is rigidly attached to the cylinder 13 and rotatestherewith. The cylinder a passes down through the hole 0 and is securelysituated in the pile A, the said hole 0 being situated in the platform0.

It will be readily seen from the foregoing description that when thelever F is raised by the action of the waves the'rods o are lifted I ooupward and being pivoted to the frictionclamps n and m causes the outerends of the said clamps to be raised. When the said clamps are raised,the jaws 2 of the clamp n grip the rim n and rotate it. The other clampm slides along at the same time without coming in contact with the saidrim n. Now when the lever F reaches the limit of its upward movement andbegins to fall the jaws as of the friction-clamp 'm grip the rim n andcontinue the rotation of the said toothed wheel. During this operationthe clamp n slides along without gripping the said rim n. It will thusbe seen by the above-described operation that the large toothed wheel K,to which the rim n is rigidly attached, is given a continuous rotarymovement which sets the mechanism in operation.

Arms 0 are pivotally attached to the shaft 70 at one end and at theother or outer end to the said friction-clamps and act as asupport forthe said friction-clamps.

The pile A, upon which the mechanism rests and rotates, is placed out inthe Water at any suitable distance from shore, and the power generatedby the foregoing mechanism may be transmitted to the shore in anysuitable and convenient manner.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In the herein-described invention, the combination of a pier, anannular flange situated thereon, a cylinder at projecting upwardlytherefrom, a cylinder B rotating around said pier, a platform 0 situatedon the top of the said cylinder B, said platform having a hole 0 throughwhich the upper end of the cylinder a projects, substantially asdescribed.

2. In the herein-described device, the combination of a pier or pile A,a cylinder rotating over said pier, platform secured to said cylinder,gear-supporting frame secured to said platform, a shaft j ournaled inlower part of said frame, a toothed wheel keyed on said shaft, acircumferential rim placed on the side of said wheel, a bracket securedto the side of said cylinder, a lever pivoted to said bracket, a buoyantfloat attached to the free end of the said lever, rods hinged at anintermediate point of said lever, friction-clamps gripping saidcircumferential rim, the said rods connecting the said friction-clampsand the operating-lever F, substantially as set forth and described.

In testimony whereof I affix my signature in the presence of twowitnesses.

DAVID F. SPANGLER.
